How did ancient people do foreskin surgery?

? According to experts, when it comes to male circumcision, if we look back at history, we will find that this minor operation is almost accompanied by the whole process of human civilization. The foreskin operation of ancient humans is a religious custom-circumcision. The method is to cut off the foreskin on the penis. Until now, circumcision is still a major event in the lives of some primitive people. Ancient Egyptian hieroglyphs used circumcised or erect male reproductive organs to represent penises. Some mummies preserved to this day still have foreskins, and some have been cut off. The difference is that human circumcision was not for health at that time, but a religious ceremony. The earliest surgical tool was sharpened stone, which is still used by most primitive people. Circumcision is very dangerous. Later, it was developed to be circumcised by specialized staff with special steel knives. The only task of these workers is to circumcise the foreskin. The completion of circumcision means that the man has determined his identity and promised to enter the scope of marriage license. It is worth noting that those nations who circumcise boys have almost no penile cancer, which has to attract the attention of modern medicine. (Editor: Junchi)
